When passing an array to a function in PHP, what is the default behavior regarding its modification within the function scope?
The array is passed by value, but only if it contains primitive types; otherwise, it's passed by reference.
The array is passed by reference, so modifications inside the function affect the original array.
The array is passed by value, creating a copy, so modifications inside the function do not affect the original array.
The behavior is undefined and depends on the PHP version.
